Melinda Smith, 35, and Jason Whitney, 43, were charged Tuesday with eight counts each of sexually abusing a child under the age of 10. They also face a count of possession while armed with a handgun.

They appeared in court on Wednesday and entered not guilty pleas.

Smith is also known as Mercedes Carrera, a porn star with an extensive number of credits on IMDB. Police say Whitney is a producer and director of several pornographic films.

Detectives from the Rancho Cucamonga police department say they were first notified of sexual acts against a girl under the age of 10 on Jan. 31. The girl was sexually abused repeatedly over four months by Smith and Whitney, according to police.

Last Friday, a search warrant served at their home uncovered evidence corroborating the girl’s statement, including a bedroom set-up where the couple could film and record various pornographic videos or web shows, methamphetamine and two loaded handguns, police said.
